The correct answer is the mouth. Digestion begins when food enters the mouth, chewed, and mixed with saliva. Food usually has complex carbohydrates such as starch in them and saliva has an enzyme called salivary amylase which can break down these complex carbohydrates into simpler molecules (i.e. dextrins). After which, these dextrins are digested further in the stomach and in the small intestine by the action of enzymes such as the pancreatic amylase which further breaks down dextrins into oligosaccharides and disaccharides. Other enzymes such as trypsin breaks down proteins into amino acids and lipase that breaks down fat into triglycerides. In the brush border of the small intestine, there are enzymes such as oligosaccharidases and disaccharidases which breaks down sugars into their most basic forms (i.e. glucose, fructose, galactose) which can be readily absorbed in the intestine. Amino acids and tricglycerides are also readilty absorbed in the intestines with the latter by the help of emulsification by bile.
Macromolecules in the mammals are of three different types, namely the carbohydrates, proteins, and the nucleic acids. Among these macromolecules, the nucleic acids are capable of self-replication. These encode the genetic information of the organism, and plays a vital role in carrying out an array of different functions of the body. One example of such nucleic acid is the RNA, or the Ribonucleic Acid.
rice=polysaccharide, grapes=monosaccharide, milk=disaccharide
Answer:
A) Dark moths had a survival advantage in rural Birmingham.
Explanation:
In the given graph, the data about dark moths are colored orange, and the data about light moths are colored green. We can clearly see this in the image I've attached below.
We can see that the percentage of recovered dark moths is greater in Dorset, while the percentage of recovered light moths is greater in Birmingham. This means that the dark moths had a survival advantage in Dorset, while the light moths had the advantage in Birmingham. This is why statement A is not supported by Kettlewell's data.
